Introduction
Welding has become an important part of modern manufacturing processes. It is used in numerous industries, from automotive manufacturing to aerospace production. One test used to ensure welding quality is the FISCO Weld Crack Test. This test involves pressing two plates together and then applying a special welding current to induce a weld joint. After the joint is created, the plates are then tested to determine if any cracks or fault lines exist. This test is used to make sure the welds are of the highest quality before any further manufacturing takes place.
Background
The FISCO Weldcrack Test was first developed by Dr. Friederich Hofschenra in Germany in the early 1900s. His method used an induction welding current to press two plates together and then measure the local temperature of the adjacent edges. In the 1940s, Dr. Friedrich Hofschremer’s method was refined and the FISCO test was approved by the German Ministry of Economics. The FISCO Weldcrack Test is now an accepted international standard for testing the weld quality of materials.
Procedure
To perform the FISCO Weld Crack Test, two plates need to be fed into a welding machine. The welding machine will apply a special welding current to the two plates to induce a weld joint. The plates are then pressed together and subjected to a series of tests. These tests include inspecting for cracks, fault lines, porosity, and poor bonding. If any of these defects are found, then the weld quality has not been met and the welding process should not proceed further.
Diagram of Procedure
The following diagram illustrates the FISCO Weld Crack Test. The two plates are placed on either side of the welding machine. The welding current is applied and the plates are pressed together. The plates are then inspected to check for any defects that may have occurred during the welding process.
Conclusion
The FISCO Weld Crack Test is a quality assurance test that is used to ensure that welds are of the highest quality. This test involves pressing two plates together and applying a special welding current to induce a weld joint. After the joint is created, the plates are then inspected for cracks, fault lines, porosity, and poor bonding. If any of these defects are found, then the weld quality has not been met and the welding process should not proceed further.
